Description:
BVR photoelectric photometry and positions are reported for 437 stars in 49
Palomar Sky Survey fields. A relation is derived between the Johnson BVR
photometry and the E and O photographic magnitudes on the Palomar plates.
The BVR photometry, the E and O magnitudes, and the 1950 positions are
presented in the accompanying catalog.
